AlphaBot2 robot building kit for Raspberry Pi 3B/3B+/4B (no Pi)

This AlphaBot2 robot kit is designed to use with Raspberry Pi 3B/3B+/4B (not included). It features rich common robot functions including line tracking, obstacle avoiding, Bluetooth/infrared/WiFi remote control, video monitoring, etc.

Thanks to the highly integrated modular design, it is fairly easy to assemble by a snap, no soldering, no wiring. After a few minutes spent on hardware assembing, you're almost there, our open source demo codes is ready to help you get started fast.

Features

AlphaBot2 employs a 2-layer structure to provide excellent stability and compatibility.

AlphaBot2-Base, the lower base chassis:

• 5-ch infrared sensor, analog output, combined with PID algorithm, stable line tracking
• Onboard modules like line tracking, obstacle avoiding, needs no messy wiring
• TB6612FNG dual H-bridge motor driver, compared with L298P, it's more efficient, more compact, and less heating
• N20 micro gear motor, with metal gears, low noise, high accuracy
• Onboard RGB LEDs, true color lighting, pretty cool

AlphaBot2-Pi, the upper adapter board for controller:

• LM2596 voltage regulator, provides the Pi with stable 5V power
• TLC1543 AD acquisition chip, allows the Pi to use analog sensors
• PCA9685 servo controller, make it more smoothly to rotate the pan head
• CP2102 UART converter, easy for controlling the Pi via UART
